Add three more teams to the 2013 MLB playoff field: The Atlanta Braves are NL East champions, the Oakland Athletics have won the AL West and the St. Louis Cardinals secured at least a wild-card berth on Sunday.

The Cardinals and Braves set their plans before their games were over. Atlanta won its division when the Miami Marlins defeated the Washington Nationals. The Cardinals played Sunday night, also having reached the postseason with the Nationals' loss.

Likewise, the A's were playing when the Texas Rangers lost to the Kansas City Royals, ending the Rangers' division hope.

Six teams remain alive in the AL wild-card. The Detroit Tigers got closer to the AL Central title.

In the NL, the Central title is the last division race, and three teams from it are either in the playoffs or close to it. The Cincinnati Reds and Pittsburgh Pirates are vying for the wide card and have an outside chance to win the division. The Nationals could be eliminated on Monday.
